PART # DESCRIPTION NOTES
43 DISSOLVED OXYGEN SENSOR - Sea-Bird polarographic membrane sensor for pumped CTD applications, 0-5 volt temperature-compensated oxygen signal. Includes plenum & complete documentation. SBE 43 can be ordered in several ways:
  • By itself; consult Sea-Bird to order interface cable or mount kit separately, if needed.
  • As an option in SBE 9plus, 16plus V2, 16plus-IM V2, 19plus V2, or 25plus listing, complete with sensor, CTD interface cable, & mount kit.
For sensor with frequency output, compatible with SBE 52-MP Moored Profiler CTD or Glider Payload CTD, see SBE 43F below. Another version of 43F is an integral part of SBE 37 MicroCAT (SIP-IDO).
SBE 43 Housing Selections — MUST SELECT ONE

SBE 43 Connector Selections — MUST SELECT ONE
43.x1x1 XSG connector

Wet-pluggable connectors may be mated in wet conditions. Their pins do not need to be dried before mating. By design, water on connector pins is forced out as connector is mated. However, they must not be mated or un-mated while submerged. Wet-pluggable connectors have a non-conducting guide pin to assist pin alignment & require less force to mate, making them easier to mate reliably under dark or cold conditions, compared to XSG/AG connectors. Like XSG/AG connectors, wet-pluggables need proper lubrication & require care during use to avoid trapping water in sockets.

SBE 43 Membrane Selections — MUST SELECT ONE
43.xx11 0.5-mil membrane, Profiling configuration (fast response membrane, includes dynamic response characterization)

See Application Note 64 for information on response times for each membrane.

SBE 43 Spares & Accessories
171491 SBE 43 interface cable, AG/RMG connectors (9plus), 0.7 m (DN 32496) These interface cables are compatible with SBE 9plus, 19plus, 19plus V2, 25, or 25plus if connecting just SBE 43 to bulkhead connector. If connecting 2 sensors to 1 bulkhead connector, a Y-cable is required in place of one of these straight cables.

Note: 172447 and 172448 are also used for integrating SBE 43 with SBE 16plus, 16plus-IM, 16plus V2, or 16plus-IM V2. However, for moored applications, Sea-Bird usually recommends SBE 63 Optical Dissolved Oxygen Sensor instead of SBE 43.
172447 SBE 43 interface cable, AG/RMG connectors (19plus/19plus V2/25/25plus), 1.1 m (DN 32496)
172218 SBE 43 interface cable, Wet-pluggable connectors (9plus), 0.7 m (DN 32654)
172448 SBE 43 interface cable, Wet-pluggable connectors (19plus/19plus V2/25/25plus), 1.1 m (DN 32654)
801617 SBE 43 Plenum Assembly, Version 2, Black Acetal In 2007, Sea-Bird transitioned from using white plastic parts to black plastic parts for SBE 43, to minimize exposure to light, improving resistance to bio-fouling. Customers may retrofit existing SBE 43s.
50126 SBE 43 mount kit for SeaCATs For mounting SBE 43 to SBE 16, 16plus, 16plus-IM, 16plus V2, 16plus-IM V2, 19, 19plus, or 19plus V2 SeaCAT.

30388 Tygon tubing, 1/2" ID x 3/4" OD, 2 m — main plumbing 30388 is main plumbing, attaches to pump, conductivity sensor, 1/2" nylon hose barb Y-fitting, etc. (photo shows 30388 tubing with SBE 9plus).
31450 Tygon tubing, 1/2" ID X 3/4" OD, 2 m, Black — main plumbing, minimizes light exposure 31450 can be used in place of 30388 plumbing tubing to minimize exposure to light, improving resistance to bio-fouling for moored applications. Sea-Bird uses this black tubing on all moored instruments (SBE 16plus/16plus V2 and 16plus-IM/16plus-IM V2 CTDs). Customers may field retrofit plumbing on existing systems.
